Is oxygen actually a waste product

[sirloxley]

Contrary to the game's title, and especially in late(r) game basis I get the impression that there are not that many useful applications for it. It just sits there and I end up venting it. Yes you need it for rockets, but as far as I see it, the limiting factor here is LH2.

I have seen hints/suggestions about O2 being useable for other purposes but I fail to see the large scale use if it.

So what do you do with your excess O2? Vent it like me?

[GluttonyMain]

If you are using electrolyser for hydrogen only than yeah, venting some of the oxygen is optimal. You save on energy from the air pump

[ManiacMike]

All excess Oxygen goes into Oxylite Refinery. Later also to Liquid Oxygen Production. When i have enough of both i dont see any other use for it. just vent it

In the early game, you may want to use hydrogen power beyond that produced as a side effect of operating a SPOM for making oxygen. In this case the oxygen is a waste.

In the mid game the oxygen can be used to make Oxylite, though the power requirements are not small, like if you're playing Super Sustainable rules and mainly using hydrogen power, you'd probably be venting a lot of oxygen to get enough hydrogen to run the process.

In the late game there's a vast disparity between the hydrogen and oxygen usage of rockets. Unlike IRL, in ONI rockets burn a lot more fuel than Oxidizer, with a Hydrogen Engine burning a 4:1 ratio of Liquid Hydrogen to Liquid Oxygen, while an Electrolyzer produces hydrogen and oxygen in a 1:8 ratio, so you actually discard about 97% of the oxygen produced by the electrolyzers when making rocket propellant.

I often build pufts ranch to get some meat and lime. Its more effective than Bristle blossom plantation by water usage, and much simpler than other sources

Longhair slickster ranching. Wish they expelled something like the other 2 morphs, like water, which would make them amazing for food production, but right now they are there as an option with no by-products.

Nope. As soon as I have sufficient other power sources, I start pumping my H2 into infinite storage. I don't use it for power unless my liquid hydrogen tanks are full. We generally produce a huge excess of H2.

Bees + saturn critter traps = hydrogen explosion. Do you even use saturn critter traps? Do you know that they produce insane amount of hydrogen? Like bonkers amount of hydrogen?

While growing, the Saturn Critter Trap produces hydrogen. The hydrogen is produced and stored internally at a rate of 167g every 4 seconds (25kg per cycle). When the plant has accumulated 33.3kg of hydrogen is released into it's environment.

This game has an electolyzer. How about a galvanic cell? I know about the hydrogen generator. Or a ferro-electrolyzer for more hydrogen...
